Description

Technical Field

[0001] This utility model relates to the technical field of crushing devices, specifically a crushing device for recycling plastic shells. Background Technology

[0002] Plastic shells are widely used components in industry and daily life, and their recycling has become a crucial part of resource recycling. Crushing equipment is one of the core pieces of equipment in the plastic recycling process, mainly used to break large or complex plastic shells into fine particles to facilitate subsequent washing, sorting, and reprocessing. Currently, various types of crushing equipment for plastic shell recycling are in use, such as those based on blade cutting, roller crushing, or hammer crushing principles, which achieve preliminary crushing of plastic materials through mechanical force.

[0003] However, existing plastic shell crushing devices still have some obvious technical shortcomings:

[0004] 1. Traditional crushing devices often employ a single crushing principle, such as cutting or crushing, which is insufficient for handling complex plastic shells with varying hardness. This is especially true when processing shells with reinforcing ribs or irregular shapes, easily leading to incomplete crushing, uneven particle size, and even accelerated blade wear due to concentrated stress. Some equipment lacks a multi-stage crushing mechanism, leaving large fragments after initial crushing, requiring repeated processing and reducing recycling efficiency and particle quality.

[0005] 2. Most devices lack built-in grading and screening functions, resulting in a mixture and accumulation of crushed plastic particles. This necessitates secondary processing using external screening equipment, increasing process complexity and equipment costs. Furthermore, qualified particles that are not screened out in time are easily subjected to repeated crushing, leading to energy waste and overheating degradation of the material, affecting the performance of recycled plastics. In addition, fixed screens are prone to clogging and cannot achieve dynamic screening during the crushing process, further limiting processing efficiency.

[0006] Therefore, in view of this, an improvement was made to the existing structure, and a crushing device for recycling plastic shells was proposed. Utility Model Content

[0007] The technical problem this invention aims to solve is the poor crushing effect; existing crushing methods cannot help sieve out the properly crushed plastic shells.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a crushing device for recycling plastic shells, including a recycling box, an inlet fixedly and through the top of the recycling box, a crushing component inside the recycling box, and a drawer slidably and through the bottom of the recycling box. The crushing component is composed of a grinding structure and a crushing structure.

[0009] The crushing structure includes a receiving rod fixedly installed inside the recycling bin. A rotating rod is rotatably installed at the bottom of the receiving rod, and a sleeve rod is fixedly sleeved on the rotating rod. Several blades are evenly distributed and fixedly installed around the sleeve rod. A screen plate is movably sleeved on the rotating rod, and the screen plate is slidably connected to the recycling bin. A drive assembly is installed inside the recycling bin below the screen plate to drive the rotating rod to rotate and the screen plate to slide up and down.

[0010] As a further embodiment of this utility model: the crushing structure includes two crushing wheels rotatably disposed inside the recycling bin, two mutually meshing gears are rotatably disposed on one side of the recycling bin, and the gears are fixedly connected to the corresponding crushing wheels by a connecting shaft, and the connecting shaft is rotatably disposed on the recycling bin, and a motor for driving one of the crushing wheels to rotate is fixedly disposed on the other side of the recycling bin.

[0011] As a further embodiment of this utility model, the top of the receiving rod is arc-shaped.

[0012] As a further embodiment of this utility model: the driving assembly includes a rotating rod II rotatably disposed inside the recycling bin, a bevel gear I fixedly sleeved on the rotating rod II, a bevel gear II fixedly disposed at the bottom end of the rotating rod I and meshing with the bevel gear I, a plurality of elliptical wheels fixedly sleeved on the rotating rod I, and the elliptical wheels pushing the screen plate, and a motor II for driving the rotating rod II to rotate is fixedly disposed on one side of the recycling bin.

[0013] As a further embodiment of this utility model, an anti-slip pad is fixedly provided at the bottom of the recycling bin.

[0014] As a further embodiment of this utility model: the movable range of the sieve plate is between the lower end of the sleeve rod and the bottom of the second bevel gear.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] 1. This utility model achieves two-stage progressive crushing of plastic shells by setting up a composite crushing component consisting of a crushing structure and a pulverizing structure. First, two meshing crushing wheels perform preliminary crushing and coarse crushing on the large pieces of plastic shells, breaking them into smaller pieces. Subsequently, these pieces fall into the pulverizing structure below, where multiple high-speed rotating blades perform further fine cutting and pulverizing. This staged processing mode of first pressing and then cutting can efficiently process plastic shells of different shapes and hardness, and is especially suitable for complex workpieces with reinforcing ribs or irregular structures. It effectively avoids problems such as uneven crushing and easy material jamming caused by a single crushing method, and finally obtains smaller and more uniform plastic particles, significantly improving crushing efficiency and effect.

[0017] 2. This utility model innovatively integrates a screen plate capable of reciprocating up and down movement into the crushing blade area, and achieves synchronous linkage with the crushing blades through a drive component. While the blades rotate to crush particles, the elliptical wheel drives the screen plate to continuously vibrate up and down with small amplitudes. Qualified particles smaller than the screen plate mesh diameter are screened out under the vibration and fall into the drawer at the bottom for collection. Larger particles that do not meet the size requirements remain above the screen plate and continue to be cut and crushed by the blades until they can pass through the screen. This design combines the crushing and screening processes into one, allowing for real-time particle sorting within the device without additional equipment, greatly simplifying the process and saving time and energy. Simultaneously, dynamic screening effectively prevents clogging of the screen plate mesh, ensuring the continuity and stability of production. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 A crushing device for recycling plastic shells includes a recycling bin 1. An inlet 101 is fixedly provided at the top of the recycling bin 1 for feeding in plastic shells to be processed. A crushing assembly is installed inside the recycling bin 1. A chute is provided at the bottom of the recycling bin 1, through which a drawer 102 for collecting the crushed material is slidably installed at the bottom of the recycling bin 1, facilitating emptying by the operator. To enhance the stability of the equipment during operation, a rubber anti-slip pad is fixedly adhered to the bottom of the recycling bin 1. The crushing assembly includes a grinding structure 2 and a crushing structure 3. The grinding structure 2 includes two grinding wheels 201 rotatably installed inside the recycling bin 1. Two meshing gears 202 are rotatably installed on one side of the recycling bin 1, and the gears 202 are fixedly connected to the corresponding grinding wheels 201 via a connecting shaft, which is rotatably mounted on the recycling bin 1. A motor 203 is fixedly installed on the other side of the recycling bin 1 to drive the rotation of one of the grinding wheels 201. When motor 203 starts, it drives one crushing wheel 201 to rotate. Through the transmission of two meshing gears 202, the other crushing wheel 201 will rotate synchronously in the opposite direction, thereby performing preliminary crushing and crushing on the plastic shell fed from inlet 101.

[0027] Please see Figure 2-4The crushing structure 3 includes a receiving rod 301 fixedly installed inside the recycling bin 1. The top of the receiving rod 301 is arc-shaped to smoothly guide the plastic blocks that fall after initial crushing by the crushing wheel 201 to the central crushing area. A rotating rod 302 is rotatably installed at the bottom of the receiving rod 301, and a sleeve rod 303 is fixedly sleeved on the rotating rod 302. Several blades 304 are evenly distributed and fixed around the sleeve rod 303. A screen plate 305 is movably sleeved on the rotating rod 302, and the screen plate 305 is slidably connected to the recycling bin 1. The edge of the screen plate 305 is slidably connected to the inner wall of the recycling bin 1 through a sliding groove or guide rail, so that it can only slide up and down and cannot rotate. Inside the recycling bin 1, below the screen plate 305, there is a driving assembly 4 that drives the rotating rod 302 to rotate and the screen plate 305 to slide up and down, for simultaneously driving the crushing and screening actions. The drive assembly 4 includes a rotating rod 401 rotatably mounted inside the recycling bin 1. A bevel gear 402 is fixedly sleeved on the rotating rod 401. A bevel gear 403, meshing with the bevel gear 402, is fixedly mounted at the bottom end of the rotating rod 402. Several elliptical wheels 404 are fixedly sleeved on the rotating rod 302, and the elliptical wheels 404 push the screen plate 305. The movable range of the screen plate 305 is between the lower end of the rod 303 and the bottom of the bevel gear 403, ensuring that its movement does not interfere with the rotation of the blades and the transmission of the gears. A motor 405 for driving the rotating rod 401 to rotate is fixedly mounted on one side of the recycling bin 1. The bevel gear 403 meshes with the horizontal bevel gear 402, thereby converting the horizontal rotational motion of the rotating rod 401 into the vertical rotational motion of the rotating rod 302.

[0028] The working principle of this utility model:

[0029] During operation, motor 203 and motor 405 are started first. The plastic shell is fed into inlet 101 and crushed into smaller pieces by the counter-rotating crushing wheels 201. The pieces then fall onto the receiving rod 301 and slide onto the screen plate 305. At this time, motor 405, through the transmission of rotating rod 401, bevel gear 402, and bevel gear 403, drives rotating rod 302 and its blades 304 to rotate at high speed, finely cutting and crushing the plastic pieces on the screen plate 305. Simultaneously, due to the rotation of rotating rod 302, the elliptical wheel 404 on it also rotates, periodically lifting and lowering the screen plate 305, causing it to produce continuous up-and-down reciprocating vibration.

[0030] Under this vibration, plastic particles pulverized to a sufficiently small size (smaller than the mesh size of sieve plate 305) pass through the sieve holes and fall into the bottom drawer 102 for collection. Larger particles that do not meet the size requirements remain on sieve plate 305 and continue to be cut and pulverized by blades 304 until they are sieved out after reaching the required size. The entire process achieves simultaneous pulverization and sieving, resulting in a high degree of automation and significantly improved pulverization efficiency and quality.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
